bin2npm

A helper cli which takes one or more binaries for different platforms and wraps them into an npm package for distribution.

Run/Install via deno (from jsr.io)

Opt1: Run directly from JSR

deno run --allow-read='.' --allow-write='.' jsr:@bjesuiter/bin2npm --config ./bin2npm.toml

Opt2: Install globally on your host machine from JSR

deno install --global --allow-read='.' --allow-write='.' -n bin2npm jsr:@bjesuiter/bin2npm

Run/Install via npm

Package URL: https://www.npmjs.com/package/bin2npm

Opt1: Run directly from npm

# with config file search
npx bin2npm

# with explicit config file
npx bin2npm --config ./bin2npm.toml

Opt2: Install on your host machine from npm

# global install
npm i -g bin2npm

# local install
npm i -D bin2npm

Run/Install via bun

Package URL: https://www.npmjs.com/package/bin2npm

Opt1: Run directly from bun

bunx bin2npm --config ./bin2npm.toml

Opt2: Install globally on your host machine from bun

# global install
bun i -g bin2npm

# local install
bun i -D bin2npm

Usage (for all: deno, npm & bun)

1. Write a config file (see: example config file)
2. Run bin2npm (only works when installed globally, alternatively use npx, bunx, or direct running via jsr) => It will search for all bin2npm.toml files inside your CWD
3. Alternatively, run bin2npm --config ./bin2npm.toml to specify a config file directly
4. Finished! If your config was correct, then your output npm package should be in your configured output dir!

Example Config

# File: bin2npm.toml
bin2NpmVersion = "0"
outDir         = "npm"

[targetPackageJson]
    name        = "bin2npm"
    version     = "0.0.6"
    description = "A cli tool by @bjesuiter which takes one or more binaries for different platforms and wraps them into an npm package for distribution. Can also be used via bin2npm package on npmjs.org"

[[binaries]]
    # path to the binary you want to wrap, based on the cwd where you run bin2npm
    path = "compiled/bin2npm_linux_x64"
    # platform should be one of nodejs's os.platform() values:
    # for Node 16 LTS: 'aix', 'darwin', 'freebsd','linux', 'openbsd', 'sunos', and 'win32'
    # see https://nodejs.org/docs/latest-v16.x/api/os.html#osplatform
    # These are only the allowed values. You have to provide the correct binary for this to work.
    platform = "linux"
    # arch should be one of nodejs's os.arch() values:
    # for Node 16 LTS: 'arm', 'arm64', 'ia32', 'mips', 'mipsel', 'ppc', 'ppc64', 's390', 's390x', and 'x64'
    # see https://nodejs.org/docs/latest-v16.x/api/os.html#osarch

[[binaries]]
    path     = "compiled/bin2npm_windows_x64.exe"

Dev Docs

Asset building for compilation

Use asset-builder from (https://jsr.io/@codemonument/asset-builder) to have the template folder available to the deno cli. Run deno task pack-assets to pack the files in /template into src/gen/assets.ts Must be used in the npm AND the deno variant of this package, otherwise this cli will not work when installed from jsr.io!

Releasing a new version (for JSR and npm)

1. Increase versions:
   1. In cli.ts for the bin2npm cli --version command
   2. In deno.jsonc for the JSR deployment of this package
   3. Of target npm package by updating the version in ./bin2npm.toml
   4. In Changelog here at the bottom of the readme
2. Run deno task pack-assets
3. Commit all changes
4. Add a new git tag for your new version and push it => will trigger the deploy-npm.yml github workflow and the publish-jsr workflow

For deploying manually, run

1. deno task compile to compile the deno scripts with the deno executable into self-contained executables
2. deno task assemble-npm => This runs bin2npm on the compiled output of itself! (Great, isn't it?!?)
3. deno task publish-npm to publish on npm
